Throughout the game you will encounter these animals in different locations. Sharks and whales can be found in the ocean and can only be killed during harpooning circumstances. The rest are found in the jungles, islands and other areas.

Animals like the White Whale and the Red Howler Monkey can only be found in certain locations on the map. Also, there are animals that can be found and killed but not skinned, like tortoises, flamingo, and other birds as well.
